LOCK.

Specification of Letters Patent.

Application filed September 24, 1915. Serial No. 52,331.

To allee/tom it may concern:

Be it known that I, SAMUEL SEGAL, a citizen of the United States, and resident of the city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements 1n Locks, eation.

This invention relates to locks, and particularly to locks which may rbe used for swinging doors in certain convenient `.situations,v as for example in connection with an outside house door whereon it may be secured upon its interior side to serve as a night lock.

The present invention is an miprovenient upon the lock disclosed in my application for Letters Patent, Serial No 21958, filed principal object is to provide said lolek with simplified, inexpensive, etticient, and nnproved means'for automatically throwing the lock-bolt into lockingf:engagenient with its keeper upon closing of the door.

VOther objects and advantages will hereinafter appear.

In the acconnninying l1:1\\'ings,-l11 igure 1 is a sectional ele'vation of the lock showing the disposition of its parts when in un'- locked state. Fig. 2 is a sectional plan view of the lock shown in Fig. 1. Fig. 3. is a view, in a reduced scale.` similar to Fig. '1, but showing the disposition of the parts of the lock when in locked state.

A cast metal casing `1 containing the locklng mechanism and constituting the lock body proper is secured, by means of. screws 2, against the inner side of a swinging door 3 which opens into the interior of a room and ,swingsabout a `vertical axis ot its hinges in the direction of the arrow, Fig. '2. A keeper -l for the lock is secured to the door-frame 5 by means of screws G. The tumbler-barrel 8 of the lock-mechanism passes through the door 3 whereby a key 9 may belinserted from the exterior to unlock the door, while at the inner side of the door it may be unlocked by turning` 'a lVhen the lock-casing 1 is secured in properly alined position against the door 3 its end p'ortion 11 which is entirely incased eX- 4tends beyond the door-edge 12 and overlaps the door-frame 5 and the keeper 4'. Within the extending end-portion 11 is-contained, a palr of cylindrical,4 bolts 13 which are conof which the following isa speci-- tical track ,ledge 2l? and extending 4the head extremity 30 to swing it-toward nected by brackets 14. to a post 15. Said cylindrical bolts are disposed vertically and have their axes concentric, and they fit against the wall of the extending casing-portion 11 which at its outermost side is convexedly formed to follow the configuration of the bolts. A frame or plate 16 forming part of the post extends therefrom into the interior of the casing 1. Said frame is provided with a groove 17 fitting over a ver- 18 cast upon the wall of casing 1, and the connecting` post 15 is litted slidably between guiding ledges 19 cast upon the casing-wall, whereby the bolts 13 together with the post 15 and frame 1G are thus guided at all sides against lateral displacement and they maybe therefore shifted in a vertical direction upwardly and downwardly, from the position shown in Fig. 1 to that shown in Fig. 3 and back.

Upon the frame 16 is pivoted a tumblerpawl ZOat 21 from where it extends vertically lownward and bears against projections `22; formed upon frame 1G, toward which projections said pawl pressed by a leaf-spring Q3 fixed head 24 and leaning against a head 25 of a detent 25 on frame 16. The lower part of the pawl 20 is provided with a ledge QG which abuts against a lug 27 of the wall when the bolts 13 are disposed in their upward position, by which means saidv bolts 'together with the frame 1V and the parts dependent therewith are maintained in their elevated state shown in Fig. 1. A lever 28 fulcrumed at 2i) upon frame 16 has a carnextremity 30 of-its arm 31 passing into .t slot 32 formed in the pawl 20 adjacent its to its pivot- 'llhe other arm of said lever exten'ls'upwardly from fulerum 29 and is provided vat its extremity 3l with aneye 35 within which 2 5 of detent 25 is pivotally fitted. Detent 25 normally abuts against a. projection Sla el arm-extremity 3-1- and it is pressed against said extremity by whereby, when the bolts 13 are 'in unlocked elevated position shown in Fig. 1, the detent is disposed rightangularly thereto and pro-l jects outside of the casing. Pressing laterallyagainst beveled extremity 25b of detent `25 toward the left, as viewed'n the drawing, rocks the vlever 28 and causes its earnthe right about' pivot 21, thereby releasing the locking-ledge 26 from casingobliquely therefrom.

is normally y the spring .23,

the lug 27 and rendering the bolts 13 and the parts dependent therewith free to move downwardly. And being thus released the bolts are caused to descend automatically to the position shown in Fig. 3, by means ofa spring 36 havingone end thereof secured to the frame 16 and its opposite end to the rim o'f casing 1. -When the bolts 13 are disposed in their lowered position the upper edge of ledge 26 is retained against thelower edge of lug 27 whereby the bolts are maintained locked' in the downward position.'

A plate 37 is secured to the shank of knob l0 and is provided with opposite arms 38 that are normally maintained in vertical disposition, as shown, by means of Vopposite springs 39, secured to pins 40 upon casing 1, pressing against opposite projections 41 formed on said plate.v By this means, also,

a semicircular snap movement may be lm-l parted to the arms-38 in the direction of the arrows, andv backwardly, Fig. 1, uponturning of the knob 10 half'a revolution, said vsprings automatically aliningr said arms in vertical disposition at each half turn of the knob.l In order to restore the bolts 13 to their elevated position, the knob 10 is turned for half a revolution in the direction of the arrows and' imparts its movement 'to the arms 38. The lower one of said arms is thereby caused to enter between the ledges 22, and while progressingr on its stroke the arm strikes the pawl 20, against a projection 43 thereof, thereby causing the pawl to swing toward the right and to become released from the lug 27. And simultaneously the arm 38 carries the-frame 16 andparts dependent therewith upwardly contrary to the pull of spring 36 and raises the bolts 13 back to theposition shown in Fig. 1. When the bolts 13 are thus restored to elevated position the pawl 201 is returned by its spring V23 in position to bear against the projections 22' and to abut against the lug 27 for maintaining said bolts in elevated position, and the lever 28 is restored to its previous disposition. An arm'44`fixed to a spindle 45'of the barrel 8 serves for raising the bolts 13 to elevated vposition by turning of the key 9. Turning of the knob 10 or'the key 9 thus raises the bolts to locked elevated positionand pressing of the 'detent 25 into the casing 1 .automatically lowers the bolts to locked lowered position.

The keeper 4, preferably lmade of cast-V metal, is provided with an angle portion 46 comprising legs 47, 48 which are fitted against the door-frame "5 and firmly secured thereto by the screws 6. When the keeper 4 is properly fitted in position its leg 47 is fitted into a recess 47a iii the inner side of the door-frame 5 and the leg 48 thereof is fitted into a recess 49 formed in the edge 50 of said frame, so that the outer surfaces of said legs are flush with the surwith each other, and the diameters of said openings are adaptable to fittingly receive the bolts l13. Upon closing oithe door 3 both of the ears 51 enter into the end-por- -tion 11 of the lock-casing 1 through notched openings 53 provided in, theside 11a of said end-portion adjacent said door, which notched openings may, as here shown, ex-

tend aroundthe remaining sides 11b, 11c of A the end-portion 11. And when securing the keeper `4-in proper position in the installation of the lock its ears 51 are alined in vsuch manerxthat when entering the receiving openingsj53 in easing 1 the centers of the ear openings 52 will register with the joint axes of the bolts 13, wherebyV upon Said bolts being immediately thereafter shifted downwardly they will enter into the openings 52 `as shown in Fig. 3. Turning ofthe knob 10 or key 9 to dispose the bolts 13 in the elevated position shown in Fig. 1 causes the door 3 to -be maintained in unlocked state so that it may be freely opened. When it is desired to lock the door it is' iirst closed, and lthereupon the upper ear 51 strikes laterally against the beveled extremity 25b of detent 25 and pressesit within the-casing v1, thereby momentarily causing the bolts Y13 to Vcontinue to retain the detentv 25 within the c'asing 1. In 'o rder to avoid this objection the detent 25 pivoted in the eye of lever 28 is contrived to be capable of swinging about said eye in aclockwise direction, as 1 viewed in the drawing, away from the stopping projection 34a andy contrary to, Athe pressure of spring 23 thereagainst. Upon the rising of the bolts to the unlocked position shown in Fig. 1, therefore the detent 25 strikes the underside of the upper ear 51 and is'thereby swung to'an inoperative position, shown by the dash and dotlines, without effecting the position or operation of the lever 28 and the pawl 20, and said detent continues to beretained in this posiy the ear 51 during the time that said earis retained within its opening, in which manner said bolts continue to be maintained in elevated unlocked state. When the door is opened and moved away from the keeper the springl23 restores the detent 25 toits Vtion and to clear the upper opening53 and l[lierative position shown, rightangularly to and said detent being pressed by said keeper o ft sefholts 13 Within the opening 53.
